Phong shading OR Normal Vector Interpolation Shading
In Gouraud shading we were doing direct interpolation of intensities although a more exact method for rendering a polygon surface is to interpolate normal vectors and then apply illumination model to all surface. This perfect method was specified by Phong and this leads to Phong shading at Normal vector interpolation shading.
Buffer Areas Required For Z-Buffer Algorithm For applying z-buffer algorithm, we need two buffer areas or two 2-Dimentional arrays: 1) Depth-buffer [i,j], to sa

To reflect the ball off of the polyline, we need to re?ect it off of the segment that had the minimum thit. But the reflection computation depends only on t hit , n, P and v, so th
What is Aspect ratio? The ratio of vertical points to the horizontal points essential to produce length of lines in both directions of the screen is known as the Aspect ratio.
Potentially entering and leaving points - P E and P L The intersection point of the line and window might be classified either like potentially leaving or entering. Before g
This renders a polygon surface by linearly interpolating intensity values across the surface. Intensity values for each polygon are matched with the values of adjacent polygon alon
